Whisking constantly, boil for 20 minutes or until thick. Remove from heat. Stir in butter and vanilla

For pie:

Use baked pie crust (see peach pie recipe). Bake at 400 degrees for 12 minutes. If you want the shape you see in the picture, shape unbaked crust in Corning ware, oven ready, bowl. Once crust has cooled, lined with 3 sliced bananas, fill with custard, then top with two sliced bananas, overlapping. Sprinkle with granulated sugar and put under 475 degree boiler to caramelize or buy a food torch and use that to caramelize the sugar on the bananas and plate.
